ABSTRACT:
A reading device reads the direction of the magnetic moment of domains in a magnetic shift register, thus reading information stored in the domains or bits in the magnetic shift register. Associated with each domain wall are large magnetic fringing fields. The domain wall concentrates the change in magnetism from one direction to another in a very small space. Depending on the nature of the domain wall, very large dipolar fringing fields can emanate from the domain wall. This characteristic of magnetic domains is used to read data stored on to the magnetic shift register. The reading device reads the direction of the magnetic moment in a magnetic shift register, thus reading information stored in the domains.
